2-Phenylpropionaldehyde (CAS 93-53-8)
2-Phenylpropionaldehyde (CAS No. 93-53-8), universally known in the aroma industry as Hydratropic Aldehyde or Phenylpropanal, stands as a critical building block. It delivers an intense, sophisticated green-floral notes with distinctive honey and almond undertones, heavily relied upon by master perfumers and global aroma compounding houses.
Because aldehydes are highly prone to air oxidation and trimerization over time, sourcing from a tier-2 broker or an uncertified trader introduces high risks of off-odors and poor shelf stability. You need a direct primary synthesis plant that controls the hydration kinetics, trace organic acidity, and inert nitrogen packaging parameters from the initial distillation cut to your blending floor. This comprehensive B2B technical guide details our structural synthesis benchmarks, factory infrastructure, and global hazardous cargo logistics control.

Industrial Applications:
Advanced Extraction & Crystallization Technology:
The primary technical bottleneck in manufacturing CAS 93-53-8 is the minimization of trace organic acids and free moisture, which act as natural catalysts for the oxidation of the aldehyde function into hydratropic acid, altering both the olfactive quality and purity. Our plant deploys a modern continuous-flow processing setup:
- Selective Rearrangement/Condensation Process: We utilize a highly selective rearrangement method starting from high-grade raw materials. The reaction is run inside automated loop reactors utilizing custom-engineered, non-heavy metal catalysts to optimize isomerization efficiency.
- High-Vacuum Short-Path Fractionation: Traditional batch atmospheric distillation subjects aldehydes to prolonged thermal stress, triggering heavy-end polymerization and a burnt off-note. Our plant utilizes multi-stage high-vacuum fractionating columns operating at low temperatures. The short contact time preserves the natural top-notes of the molecule.
- Anhydrous Nitrogen Padding Loop: The entire purification, cooling, and drumming sequence operates inside fully enclosed, stainless steel (SUS316L) configurations under a continuous positive-pressure shroud of ultra-dry nitrogen.
Production Capacity and Robust Inventory Program:
We specialize in transforming complex chemical reactions into dependable, high-volume commercial streams for global markets:
- Annual Output Scalability: Our dedicated continuous synthesis lines generate up to 6 hundred metric tons of high-purity DBU annually, ensuring uninterrupted supply.
- Strategic Buffer Stocks: To protect international buyers against volatile cross-border shipping timelines, we maintain a permanent, temperature-regulated buffer inventory of not less than 5 metric tons at our central logistics hub. Bulk shipments are ready for compliance validation and port dispatch within 48–72 hours.
- Batch Homogeneity: Continuous production guarantees absolute homogeneity, meaning your formulation teams can maintain standardized blending recipes without adjusting for batch-to-batch structural variance.

Plant Infrastructure & Scalable Production Capacities:
We actively protect international chemical supply chains and contract fragrance houses from sudden raw material shocks and environmental compliance restrictions:
- Annual Plant Throughput: Our dedicated fractionating and organic synthesis lines yield up to 1,000 Metric Tons of Hydratropic Aldehyde annually.
- Silo Bulk Reserves: We operate a centralized bulk storage terminal equipped with automated nitrogen padding and real-time gas monitoring systems, maintaining a rolling buffer stock of 50 to 200 tons to fulfill urgent air or ocean freight orders.
- Comprehensive Regulatory Passports: Our facility operates in full alignment with ISO 9001 (Quality Management), ISO 14001 (Environmental Safety), and complete global compliance matrices. We offer full support for international client audits (On-site or via secure remote video validation).
Packaging and shipping
Because 2-Phenylpropionaldehyde is classified as a hazardous chemical substance under international maritime codes due to its environmental properties and flashpoint characteristics (UN 3082, Class 9 Miscellaneous Dangerous Goods, Packing Group III), it requires rigorous mechanical and legal handling protocols:
- Industrial Packaging Selections:
- Closed-head, heavy-walled HDPE drums or fluorinated steel drums containing 200 kg net weight.
- UN-approved Intermediate Bulk Containers (IBC Totes) holding 1,000 kg net weight, completely light-shielded.
- Bulk liquid delivery via certified ISO Tanks for multi-ton contract accounts.
- Global Transportation Footprint: Our factory is linked directly to major global deepwater container terminals and rail junctions. We handle all Dangerous Goods (DG) declarations and maritime safety checks under flexible Incoterms, including FOB, CFR, CIF, and door-to-door DDP/CIP agreements with complete customs clearance support.
FAQ
- Q1: Why is controlling the acid value so critical for CAS 93-53-8 in B2B procurement?
A: High acid values indicate that the product has already begun oxidizing into hydratropic acid. This not only drops the active purity assay but also drastically diminishes the top-note impact of the aroma chemical, introducing a sour, off-odor that disrupts fine fragrance compounding. Our strict nitrogen blanketing ensures the lowest starting acid levels in the industry. - Q2: What are the optimal storage guidelines to maximize the shelf life of Hydratropic Aldehyde?
A: The material should be stored in its original, unopened packaging in a cool, dry, and well-ventilated warehouse, preferably at temperatures between 15°C to 25°C. Avoid direct exposure to sunlight and heat. Once a drum is opened for partial use, it should be re-purged with dry nitrogen before resealing to prevent air oxidation. - Q3: What is the direct factory Minimum Order Quantity (MOQ) for export?
A: Our standard sea-freight export MOQ is 1 full pallet (containing 4 heavy-duty drums, approx. 800 kg net weight). For global manufacturing enterprises conducting initial scale-up validation trials or pilot-scale synthesis runs, custom air-freight approved validation lots can be authorized through our trade division.
